SELF-FEED LETTERING-STAMP PAD. I

Specification of Letters meat.

To all whom it may concern.

Be it known that I, ALBERT B.\J()NES, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Im rovements in Self-FeedLettering-Stamp ads, of which the following is a specification.

My invention relates generally to the art of printing, and moreparticularly to a printing element in the'nature of a stamp orimpression pad that is provided with an ink applying member that isadapted to make an impression upon the surface to which the pad isapplied.

The principal objects of my'invention are to provide a relatively simpleand inexpensive stamp or impression pad by means of which letters,figures and similar characters may be easily and quickly printed upon asurface; to provide. a. printing element having an absorbentink-carrying member, embedded in its under surface to form the body ofthe printing or impression member of rubber or analogous elasticmaterial so as to facilitate the printing operation; to provide theprinting or impression member with means for maintaining a constantsupply of ink to the absorbent ink applying member; and further, toprovide a printing or 1mpression member that may be very convenientlymanipulated, and which will be very effective in performing its intended functions.

With the foregoing and other objects in vlew, my invention consists incertain novel features of construction and arrangement of parts thatwill be hereinafter more fully described and claimed, and illustrated inthe accompanying drawings, in which Flgure 1 is a perspective view of aprinting member of my improved construction.

Fig. 2 is a view looking against the under side of the printing memberand showin the absorbent ink applying element positioned in said member.

Fig. 3 is a crosssection taken on the line 3-3 of Fig. 1.

Fig. 4 is a detail cross section showing the body of the printing membercompressed so as to force the under face of the absorbent ink applyingelement into contact with the surface that is being printed upon.

Fig. 5 is a top plan View of a modified form of my improved printingmember.

Fig. 6 is a cross section taken on the line ec of Fig. 5.

Fig. 7 is a horizontal section on a reduced scale, and which section istaken on the line 7-7 of Fig. 6.

Referring by numerals to the accompanying drawings, and moreparticularly to the construction illustrated in Figs. 1 to 4, inclusive,1O designates a substantially rectangular block or body of rubber oranalogous elastic material in the underside of which is formed a groove11 havin the shape ofthe character that is to be printed, and saidgroove being preferably dove-tail shape in cross section. Positioned insaid groove is a body 12 of absorbent material such as felt, and whichis adapted to receive and retain. in moist condition printing ink or thelike. The under surface of the absorbent body 12 is slightly inset withrespect to the under surface of the elastic body 10, so that inperforming the printin operation sufficient pressure must be a plie tothe top of body 10 to compress sai body and move the under surface ofthe ink carrying pad 12 into contact with the surface to which thecharacter is being applied (see Fig. 4). The printing or impressionmembers may be made in various sizes and they may be used'individually,and the pressure necessary to produce an 1mpression may be applied bythe hand, or a number of the blocks may be set up and locked in asuitable form in order to print the desired characters. v

In the modified construction illustrated in Figs. 5 and 7 inclusive, anelastic block 10" is provided in its under side with an absorbentink-carrying member 12 and formed in the upper portion of the body 10 isa pocket or recess 13 that receives a collapsible receptacle 14,preferably of rubber, and which contains a' supply of ink. The lower endof this collapsible ink container communicates with a short tubularmember 15, from the lower end of which leads outwardly through the lowerportion of body 10" a series of ink distributing tubes 16, the outerends of which terminate at various points in the absorbent member 12.Located on top of body 10, above the recess 13, is a plate 17, throughwhich passes the lower portion of a communicates with the chamberwithin. collapsible member 14, and disposed within the up er end of thisduct is a suitable inletva ve 21 which permits a supply of ink to bedelivered through said duct into the colla sible container. Shank 18 isprovided with a disc 22 having a knurled edge, thereby providing meansfor moving the head 19 downwardly in recess 13 to force ink from thecollapsible container 14 outwardly through the branch pipes 16 and intothe absorbent body 12. Thus, each printing member is provided with meansfor readily supplying the absorbent ink applying member with ink andenabling the device to be used indefinitely.

A stamp or printing member of my improved construction is comparativelysimple,

may be easily and cheaply produced, and provides efiicient means foreconomically producing signs, advertising matter and the like, andparticularly printed matter that is frequently changed or renewed.

It will be readily understood that minor changes in the size, form andconstruction of the various parts of my improved stamp or impression padmay be made and substituted for those herein-shown and described withoutdeparting'from the spirit of my invention, the scope of which is setforth in the appended claims.

I claim as my invention:

1. A printing member, comprising an elasti'c body, and an absorbentink-retaining member seated in the under side of said body, the underlaw of which absorbent inkretaining member is slightly inset withrespect to the under face of the elastic body.

2. A printing member, comprising an elastic body, an absorbentink-retaining member seated in the under side of said body, the underface of which absorbent ink-retaining member is slightly inset withrespect to the under face of the elastic body, and means carried by saidelastic body for supplying said absorbent member with ink.

3. An impression producing member, comprising an elastic body providedin its under side with a dove-tailed recess, a body of absorbentink-retaining material positioned within said recess, and the under faceof which absorbent body is inset with respect to the under face of theelastic body.

4. An impression producin member, comprising an elastic body provided inits under side with a dove-tailed recess, a body of absorbentink-retaining material positioned within said recess, and means carriedby said elastic body for supplying said absorbent body with ink.

5. An impression producing member, com prising an elastic'body, anabsorbent body seated in the under side thereof, a collapsible inkcontainer carried by said elastic body, and ducts leading from said inkcontainer to said absorbent body.

6. An impression producing member, comprising an elastic body, anabsorbent body seated in the under side thereof, a collapsible inkcontainer carried by said elastic body, ducts leading from said inkcontainer to said absorbent body, and means for supplying pressure tosaid collapsible body.

In testimony whereof I have signed ng name to this specification.

A. B. JONES.
